A small uncrewed submersible is used to work in deep water to explore and collect samples of the seabed. What is the pressure the submersible must be able to withstand while working at the bottom, given the depth of the sea floor is 6.70 km and assuming the density of seawater is 1.0273 g/cm3 and constant all the way down? (consider the atmospheric pressure, right above sea level, is 101.3 kPa and that g=9.80 m/s2)
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
